Jungle Tree Sapling negative farming ratio

So I just started testing out Minecraft 1.14 on a private nitrado survival server with some friends and I wanted to make my Island a jungle. Therefore I travelled 500 Blocks for half an hour to finally locate a jungle. After bringing some jungle saplings back home and planting them + waiting for them to grow, i got 2 saplings back out of 4 planted saplings. I dont think this is intended and if it is, I would say tahts pretty shitty because youd have to cut down two trees in the real jungle to get one tree to your place, which is a very annoying process and doesnt make me enjoy the game. Also I dont wanna travel 10000 Blocks over and over again
